Title: Polyphase sync. machine drive with rectifier supply - uses externally commutated rectifier and polyphase rotor excitation via slip rings
Inventor: BOEHRINGER ANDREAS PROF DR ING
IPC: H02P25/024
Filed: 1974-03-20
Abstract: The rotary converter machine is intended for driving synchronous machines whose two, theree or polyphase stator is supplied by electrical energy from an externally commutated converter. The polyphase machine rotor is excited such that it rotates in the required direction and delivers its full torsional moment from zero up to the maximum speed without the converter coupled to the machine stator needing forced commutation. The machine therefore operates simply andreliably. The connection between the polyphase system supplying the rotor windings and the rotor windings themselves is achieved either by using slip rings or by a contactless transformer arrangement.

Title: Device reducing maximum load on loudspeakers - automatic load reduction is applied in certain frequency ranges
Inventor: KLINGELNBERG ARNDT
IPC: H04R3/00
Filed: 1974-04-01
Abstract: The system comprises loudspeakers, power amplifiers and, possibly, present frequency filters. The automatic load reduction is continuous and applied through a control circuit whose input quantity can be a voltage, a current or the wattage. This input quantity is evaluated as a function of frequency. Response times of this control circuit are adapted to dynamic overload properties and physiological audibility. This load reduction is achieved by controllable frequency filters. Level of the filtered signal, cross-over frequencies, filter steepness or a combination of the above can be varied. The loudspeakers can be of smaller dimensions that would normally the use without distortions being audibly discernible.

Title: Overpressure protection for oil filled switchgear vessel - uses partly evacuated hollow element with breaking points in switchgear vessel
Inventor: NICKE WOLFGANG DIPL ING
IPC: F17C13/12
Filed: 1974-11-02
Abstract: The safety device located in the wall of an oil filled switchgear vessel responds to the overpressure to generate a control signal to open a valve connected to an expansion chamber. The pressure response element consists of two cup shaped shells (2) welded (3) to form a closed volume, partly evacuated. The bottom shell has a central region in the form of a bursting disc (5), rated to shear under a specified pressure. As the unit is set into the wall of the vessel, an internal overpressure causes the disc (5) to burst. Pressure within the unit increases and pressure responsive switch (6) or valve reacts to open the valve (7) located in a line between the pressure vessel and the expansion chamber.

Title: Pressure regulator for fuel atomiser on large furnace - incorporated control point setting gives greater range of control
Inventor: GOERTZ EGON
IPC: F23D11/26
Filed: 1974-12-18
Abstract: To control the atomizing of the fuel at the burner nozzle, the pressure is controlled in a pressure chamber by a spring-loaded needle valve in the fuel supply connector duct. The control point is set by the position of a stop in the path of a collar on the valve stem. A magnetic valve connector allows the pressure to be released promptly when the burning stops. Compressed air connector supplements the pressure at the lowest rates of fuel supply. The device claims a greater range of control than when using known methods.
